这是一道人教版小学五年级的数学题,请根据题目信息,用简单易懂的话生成一条解题视频。 1.解题思路讲解步骤如下: (1)审题,回顾平行四边形面积公式 (2)强调计算平行四边形面积使用的是一组对应的底和高(互相垂直),因此需要找出5米对应的底边 (3)结合周长概念、对边相等特点,分析周长、邻边、底边的关系 (4)使用底边=(周长-邻边-邻边)÷2计算底边,并说明7、5是一组对应的底和高 (5)使用底乘高计算面积 (6)总结 2.根据上述解题思路,在讲解时需要生成对应的“图形动画演示视频”。 ---**Question Stem:** 如图,小白测量出学校一个平行四边形花坛的周长是26米,同时他还测量出了这个花坛的一条边和一条高。这个花坛的面积是多少平方米呢? (单位: 米) **Options:** (No options are provided in the image.) **Other Relevant Text:** * **Unit:** 米 (meter) for perimeter and side/height lengths. The question asks for the area in 平方米 (square meters). **Chart/Diagram Description:** * **Type:** Geometric figure (a parallelogram with its height indicated). * **Main Elements:** * **Shape:** A parallelogram, depicted with its base aligned horizontally. * **Lines:** * Four solid lines form the sides of the parallelogram. * One dashed vertical line inside the parallelogram, originating from the top-left vertex and extending downwards to the bottom base. This dashed line represents the height. * **Angles:** A small square symbol at the intersection of the dashed height line and the bottom base, indicating a right angle (90 degrees). * **Labels:** * The dashed height line is labeled with the number '5'. * The slanted side on the right of the parallelogram is labeled with the number '6'. * **Relative Position:** The height (labeled 5) is perpendicular to the base. The side labeled 6 is one of the non-parallel sides of the parallelogram.
